i have a xfx 750i mobo and a xfx radeon HD 5670 gfx card. the current setting on my pci-e timer is 64 set in the bios, can i change that to something higher? will it help preformance on my gfx card? im kinda confused by it lol so any helpw ould be greatly thanked

PCI latency timers are a method to allow PCI bus-mastering devices to share the PCI bus so that PCI devices won't use such a large portion of the available PCI bus bandwidth that other devices aren't able to get needed work done.

If you have problems with your audio (usually onboard) clicking (while overclocking especially) then setting PCI latency timings to a more mid-range can help set the PCI bus fairly and allow for concurrent requests to be handled in que, giving the audio a better chance to respond to the signal reqeust and hence data delivery.

Hence the audio and other PCI bus issues that can be problematic, and especially so in an overclocked system which can often be attributed to the PCI latency settings.

If the Latency Timer is set too low, then PCI devices will interrupt their transfers unnecessarily often which will effect performance. If it's set too high, devices that require frequent bus access may overflow their buffers and lose data. This is where you will hear crackles in sound and dropped packets in Lan data transfers or web access

The bar graph shows the Current Latency value over time. Each bar represents the maximum DPC latency occurred within one second. The most recent value is shown as the right-most bar. Every second, bars are scrolled from right to left and a new bar is added at the right-hand side.

Are you talking about the chart at the linked site?
The chart in the dpc latency checker gives you an idea if you have a device, usually on the pci bus that is stealing or hogging the bus and not releasing the bus resources to any other device that signals it needs access.

For instance, say you video card needs to sent some data across the bus, but the audio card is saying not yet, well the video card has to do something so, it either dumps it or releases the oldest... boom, dropout and stutter. But, your sound was smooth, because audio hog had his time.

Could be reversed and you would get audio stutter and drops.

Editsegalaw19800> yeah, that would be easier, but I was already typing...slowly.

Its like if youre in urgent need of toilet use because youre going to vomit after drinking too much but theres already someone in the bathroom telling you "Wait it wont be long!"
Then you end up droping it in front of the door
